Book Description
Double heterostructures with spontaneously formed periodical (SFP) InGaAsP/GaAs active regions have been grown. The dependence of photoluminescence (PL) and electoluminescence (EL) properties of SFP InGaAsP/GaAs structures on excitation level and temperature have been investigated. From analysis of linear polarization rate spectral dependencies of PL SFP InGaAsP/GaAs structures it have been determined that domains with different solid phase composition have lattice mismatch (delta alpha) value of opposite sign. Threshold current density 50 A/cm2 at 77 K have been obtained in laser structures. Strong saturation of longwavelength emission hand intensity in room temperature PL and EL spectra with the increase of excitation level have been revealed.

Book Description
It was in 1986 that INSPEC (The Information Division of the Institution of Electrical Engineers) published the book Properties of Gallium Arsenide. Since then, major developments have taken place. This third edition is comprised of 150 specially commissioned articles contributed by experts from the USA, Europe and Japan.

Book Description
The present book on electrical, optical, magnetic and thermal properties of materials is in many aspects different from other introductory texts in solid state physics. First of all, this book is written for engineers, particularly materials and electrical engineers who want to gain a fundamental under standing of semiconductor devices, magnetic materials, lasers, alloys, etc. Second, it stresses concepts rather than mathematical formalism, which should make the presentation relatively easy to understand. Thus, this book provides a thorough preparation for advanced texts, monographs, or special ized journal articles. Third, this book is not an encyclopedia. The selection oftopics is restricted to material which is considered to be essential and which can be covered in a 15-week semester course. For those professors who want to teach a two-semester course, supplemental topics can be found which deepen the understanding. (These sections are marked by an asterisk [*]. ) Fourth, the present text leaves the teaching of crystallography, X-ray diffrac tion, diffusion, lattice defects, etc. , to those courses which specialize in these subjects. As a rule, engineering students learn this material at the beginning of their upper division curriculum. The reader is, however, reminded of some of these topics whenever the need arises. Fifth, this book is distinctly divided into five self-contained parts which may be read independently.

Book Description
This reference book provides a fully integrated novel approach to the development of high-power, single-transverse mode, edge-emitting diode lasers by addressing the complementary topics of device engineering, reliability engineering and device diagnostics in the same book, and thus closes the gap in the current book literature. Diode laser fundamentals are discussed, followed by an elaborate discussion of problem-oriented design guidelines and techniques, and by a systematic treatment of the origins of laser degradation and a thorough exploration of the engineering means to enhance the optical strength of the laser. Stability criteria of critical laser characteristics and key laser robustness factors are discussed along with clear design considerations in the context of reliability engineering approaches and models, and typical programs for reliability tests and laser product qualifications. Novel, advanced diagnostic methods are reviewed to discuss, for the first time in detail in book literature, performance- and reliability-impacting factors such as temperature, stress and material instabilities. Further key features include: practical design guidelines that consider also reliability related effects, key laser robustness factors, basic laser fabrication and packaging issues; detailed discussion of diagnostic investigations of diode lasers, the fundamentals of the applied approaches and techniques, many of them pioneered by the author to be fit-for-purpose and novel in the application; systematic insight into laser degradation modes such as catastrophic optical damage, and a wide range of technologies to increase the optical strength of diode lasers; coverage of basic concepts and techniques of laser reliability engineering with details on a standard commercial high power laser reliability test program. Semiconductor Laser Engineering, Reliability and Diagnostics reflects the extensive expertise of the author in the diode laser field both as a top scientific researcher as well as a key developer of high-power highly reliable devices. With invaluable practical advice, this new reference book is suited to practising researchers in diode laser technologies, and to postgraduate engineering students.

Book Description
Nanowires are attracting wide scientific interest due to the unique properties associated with their one-dimensional geometry. Developments in the understanding of the fundamental principles of the nanowire growth mechanisms and mastering functionalization provide tools to control crystal structure, morphology, and the interactions at the material interface, and create characteristics that are superior to those of planar geometries. This book provides a comprehensive overview of the most important developments in the field of nanowires, starting from their synthesis, discussing properties, and finalizing with nanowire applications. The book consists of two parts: the first is devoted to the synthesis of nanowires and characterization, and the second investigates the properties of nanowires and their applications in future devices.

Book Description
The highly acclaimed Encyclopedia of Analytical Chemistry provides a much needed professional level reference work for the 21st Century. Encyclopedia of Analytical Chemistry is the most comprehensive analytical chemistry reference available, covering all aspects from theory and instrumentation through applications and techniques. The chemistry and techniques are described as performed in the laboratory (environmental, clinical, QC, research, university), in the field or by remote sensing. The level of detail is similar to that of a lab protocol and together with the cited references, will support the analysis of complex inorganic, organic and biological structures by academic and industrial researchers. Encyclopedia of Analytical Chemistry also enables preparation of procedures, protocols and "cookbooks" by managers and staff of laboratories. Encyclopedia of Analytical Chemistry comprises over 600 articles, arranged alphabetically by topic, in approximately 14000 pages, in 15 volumes. Features: * Outstanding authorship and the highest calibre editors * Excellence of peer-review * Article Summaries * Over 6500 illustrations, many in colour * Extensive cross-referencing to facilitate navigation between articles * Extensive bibliographies with up-to-date references Encyclopedia of Analytical Chemistry is the essential cross-disciplinary reference work for all analytical chemists in academia and industry. All fields of chemical research are covered: analytical, organic, physical, polymer, inorganic biomedical, environmental, pharmaceutical, industrial, petroleum, forensics and food science.

Book Description
The aim of the work is give an overview of the activity in the field of Photonic Crystal developed in the frame of COST P11 action . The main objective of the COST P11 action was to unify and coordinate national efforts aimed at studying linear and nonlinear optical interactions with Photonic Crystals (PCs), without neglecting an important aspect related to the material research as idea and methods of realizations of 3D PC, together with the development and implementation of measurement techniques for the experimental evaluation of their potential applications in different area, as for example telecommunication with novel optical fibers, lasers, nonlinear multi-functionality, display devices, opto-electronics, sensors. The book contains contributions from authors who gave their lecture at the Cost P11 Training School.
